Pre-Assignment Details

Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

1814 were randomized 1:1:1 to treatment arms A, B, and C. Results reported for 1809 eligible participants; 5 were subsequently found ineligible and excluded from all analyses.

Reporting Groups

Description

Arm A: ATV/RTV + FTC/TDF

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

Intention to treat: All eligible participants were included in the baseline characteristics.

HIV-1 RNA was calculated as the geometric mean of the two most recent HIV-1 RNA (log 10 copies/mL) obtained on or before study entry. In the event that these two values differed by more than 1log10 copy/mL, the outlying value (based on review of all HIV-1 RNA levels available prior to study entry by the study virologist) was excluded and baseline determined by the remaining sample. Note that screening HIV-1 RNA values were not sued in the calculation of baseline HIV-1 RNA levels.

CD4+ T-cell counts were calculated as the mean of the two most recent values available on or before study entry.
